“…Recently it was demonstrated the genetic diversity and relationships between clonal tea cultivars in China, and the main breeding programs strategies to this species were also reviewed . Chemical methods for the selection of the tea superior individuals, based on their catechin content have been successfully used . The data obtained in this study may be useful to support mate conservation strategies and breeding programs.…”

The aim of this study was to evaluate the phytochemical and genetic diversity, relationships and identification of mate (Ilex paraguariensis A.St.-Hil.) elite genetic resources belonging to the Brazilian germplasm collection and mate breeding program. Mate has been studied due to the presence of phytochemical compounds, especially methylxanthines and phenolic compounds. The samples were collected from the leaves of 76 mate elite genetic resources (16 progenies × 5 localities). Total DNA was extracted from mate leaves and 20 random primers were used for DNA amplification. Methylxanthines (caffeine and theobromine) and phenolic compounds (chlorogenic, neochlorogenic, and criptochlorogenic acids) were quantified by HPLC. The genetic divergence estimated was higher within (92%) than among (8%) the different populations. Analysis of genetic distance between origins provided the formation of two groups by UPGMA cluster analysis, with higher polymorphism (94.9%). The average content of caffeine ranged from 0.01 to 1.38% and theobromine of 0.10 - 0.85% (w/w). The caffeoylquinic acids concentrations (1.43 - 5.38%) showed a gradient 3-CQA > 5-CQA > 4-CQA. The coefficient of genetic variation (CVg) was of low magnitude for all mono-caffeoylquinics acids. Significant correlations (positive and negative) were observed between the phytochemical compounds. Genetic diversity analysis performed by RAPD markers showed a greater intra-populational diversity; genetic resources with low caffeine and higher theobromine content were identified and can be used in breeding programs; the correlation between methylxanthines and phenolic compounds can be used as a good predictor in future studies.

“…In the light of these unique benefits the tea cultivation area in Korea and elsewhere is rising each year. Green tea consumption among Korean population has now increased owing to its potential health benefits (Kim et al 2010;Jung et al 2013). Thus the demand for tea cultivation by alternative methods has increased.…”

Effects of mineral salts (N, P, K, Ca 2+, Mg 2+, and Fe 3+) on the shoot growth and metabolite production of tea tree were studied using in vitro culture techniques. Among mineral salts, H2PO4-was the most important for enhanced growth rate of tea tree, while Mg 2+ and Ca 2+ did not affect plant growth. Removal of NH4 + and NO3 from the culture medium enhanced shoot multiplication compared to other treatments. Metabolite production was variable depending on mineral types and concentration. Removal of Ca2+ decreased the production of caffeine; however, other treatments did not influence its production. Ca 2+, NH4+ and Fe 3+ were important factors for catechin production in tea tree. These results can be used as the basis for development of technical soil controls suitable for tea tree cultivation in the future.
